RSA – not only for civil engineers!!

As we all know „Autodesk Robot Structural Analysis” is a powerful and very useful tool of civil engineers. Thanks to his tools and very intuitive interface even a beginner can use it. But as I will present RSA can be useful not only for civil engineer.

Thanks to possibilities of checking and studying stresses, and others important results, RSA can be use also in other domain of engineering.

An example from live.

Calculation of steel beam which is a part of whole crane system.

General view of steel beam.

Presented beam is a part of hole crane structure,  it is not a typical civil engineering element. On the top plate, we have two moving loads. Loads are representing wheels of main crane part.

Thanks to possibility of study stresses in element we are able to check if adopted solution of beam is correct. If shape of element behave correctly at a given load. By using „Maps of stresses” , in a very easy way we are able to see whether the boundaries of stresses are not exceeded.

Not only stresses in element can be study. RSA is giving to us a possibility of checking displacements. Results which are very important in structures, where all tolerances should be quite small.

By selecting the worse position of forces,  we can see in what way our beam is behaving. How big is displacement.

Displacements.

By checking the displacement, we will know if  tolerances are within acceptable limits.

On that small example we see that „Robot Structural Analysis„, can be use with great success in others engineering domains.

AutoCAD Structural Detailing 2009

Marea parte a inginerilor structuristi, daca nu chiar toti, sunt familiarizati cu vechiul program AutoCAD oferit de cei de la Autodesk. In paralel si dependente de primul program amintit, Rcad-urile au fost o madalitate de inlesnire a detalierii. Rcad Otel, Rcad Beton si Rcad Formwork au fost dezvoltate de Robobat pe parcursul existentei sale ca firma independenta. Odata cu achizitionarea firmei poloneze de catre gigantul Autodesk inevitabila contopire a produselor s-a produs.

Avem de a face cu AutoCAD Structural Detailing 2009, o versiune a AutoCAD-ului special creat pentru ingineria structurala.

Modulul STEEL permite crearea rapida si generarea eficienta a documentatiei tehnice pentru structurile metalice, incluzand desene finale si cantitati de materiale. Modulul FORMWORK faciliteaza crearea unor modele dinamice si a unor planuri de cofraj necesare structurilor din beton. Modulul REINFORCEMENT automatizeaza definirea si genrearea barelor de armatura pentru toate tipurile de elemente. Toate cele trei module sunt perfect completate de optiunile prezente in programul de baza AutoCAD.

Suita se regaseste, alaturi de Revit Structure in pachetul complet denumit AutoCAD Revit Structure Suite 2009. Legatura dintre Structural Detailing si Revit Structure este evidentiata prin intermediul BIM (Building Informational Modeling), si va servi drept un aspect important al articolelor noastre viitoare.
